methemoglobinemia/edema

A case of nonimmune hydrops fetalis resulting from fetal methemoglobinemia is presented. A woman with a pregnancy at 17 weeks' gestation was admitted after combustion gas intoxication. Although the mother totally recovered, the fetus showed signs of nonimmune hydrops fetalis at follow-up. Fetal

Methemoglobinemia is characterized by an increased level of methemoglobin (MetHb) in the peripheral blood. MetHb levels increase after tumescent anesthesia and need to be monitored. If a patient becomes symptomatic and/or the MetHb levels increase >10%, intravenous injection of an antidote is

Few health care professionals realize that topical anesthetic spray can cause methemoglobinemia. We describe a 56-year-old woman who was transferred to our emergency department when severe cyanosis and chest pain developed after administration of topical oropharyngeal benzocaine and lidocaine during

Methemoglobinemia, an uncommon hemoglobinopathy, affects oxygen transport, causing tissue hypoxia. In the perioperative period, methemoglobinemia is often overlooked as a cause of low oxygen saturation, often mistaken for the more common causes of hypoxia, such as atelectasis, pulmonary edema, or

A 19-year old woman ingested an unknown amount of sodium azide (NaN3). The earliest symptoms were nausea and loss of vision. Within a few hours her clinical features were dominated by central nervous system signs, acute pulmonary edema, lactic acidosis, and hypothermia. The patient died within 12

A collective nitrous fumes poisoning (five cases) is reported. Two patients (case 3 and case 4) were comatose, in severe respiratory distress. Shock and slate blue cyanosis were noted. Physical examination and chest X ray revealed acute pulmonary edema-Methemoglobin levels were 71,3% (case 3) and

Acute acetaminophen intoxication in the cat was studied to characterize the antidotal profile of acetylcysteine. Toxicosis was associated with cyanosis, hyperventilation, depression, and facial edema. Abnormal laboratory findings were methemoglobinemia and elevated serum glutamic-pyruvic

An 11-year-old, spayed female Dalmatian was presented with suspected acetaminophen toxicosis. The dog was severely depressed. Methemoglobinemia, facial edema, and hemoglobinuria responded to treatment with intravenous fluids, N-acetylcysteine, ascorbic acid, and sodium bicarbonate. There was no

A seven month old domestic shorthaired male cat was presented with a known history of acetaminophen ingestion. Clinical findings included icterus, depression, hypothermia, tachypnea and pronounced edema of the head and neck. Treatment was aimed at providing substrate to assist in conjugation of the

Methylene blue is commonly used as a tracer in sentinel lymph node mapping for many malignant diseases or chromopertubation during gynecologic laparoscopy. In contrast with other blue dyes such as patent blue V or isosulfan blue, methylene blue rarely causes an allergy-like reaction in patients

Acute tannic acid toxicity was studied in 6 adult Merino ewes by administering 7-10% (w/v) tannic acid solution once into the abomasum via an abomasal fistula at dose rates of 0.5, 1.0 or 2.0 g tannic acid/kg body weight. Samples of blood, urine and abomasal fluid were collected over a 48-h period

Two patients developed acute oliguric renal failure following paraphenylene-diamine intoxication. The associated clinical features included vomiting, angioneurotic edema, cyanosis, intravascular hemolysis and methemoglobinemia. Therapeutic dialysis and symptomatic management was followed by complete

Acute acetaminophen intoxication was studied in the dog to characterize pathogenesis and in the mouse as a model for antidotal research. In the dog, overt toxicity was manifested principally by cyanosis, facial and paw edema, gastrointestinal disturbance, and coma. Typical laboratory findings were

The eutectic mixture of lidocaine and prilocaine (EMLA, APP Pharmaceuticals, LLC.) is an anesthetic cream frequently used by dermatologists. Although side effects of EMLA are usually mild local skin reactions (ie, edema, pallor, erythema), more severe complications can be encountered including

A simple continuous wave near-infrared algorithm for estimating local hemoglobin oxygen saturation in tissue (%StO2) is described using single depth attenuation measurements at 680, 720, 760, and 800 nm. Second derivative spectroscopy was used to reduce light scattering effects, chromophores with
